It was reported that on (b)(6) 2023, a 21mm epic aortic valve was implanted in a patient with a history of shortness of breath on exertion and severe aortic stenosis (ava 0.6cm2, vmax 4.1m/s, pgmax 67.0mmhg, pgmean 41.6mmhg).Max velo.=2.88 m/s, max pg=33.2mmh, mean pg=18.4mmhg, eoa=1.47 cm2, dvi=0.28, at=83msec.Ar(-).On (b)(6) 2023, echocardiograms were performed.Lv:dd/ds 40.2/27.7 dilation (-), asynergy(-)ef: 59.4% (teichholz method) 61.9% (simpson method) la: enlargement (-), obvious thrombosis (-) right cardiac system enlargement (-), right ventricular load (-) ivc enlargement (-) pleural effusion (-), pericardial effusion (-).The patient discharged from facility (b)(6) 2023.On (b)(6) 2023, the patients warfarin was discontinued.On (b)(6) 2023, the patient had sudden elevation of nt-probnp was observed in ambulatory follow-up, and dyspnea developed.Heart failure was suspected and diuretic increased.On (b)(6) 2023, an echocardiogram was performed.Max velo.=6.1 m/s, max pg=149 mmhg, mean pg=90 mmhg, eoa=0.4 cm2, dvi=0.12, at=160 msec.Aortic regurgitation trivial.On (b)(6) 2023, the patient respiratory distress improved.Thrombus valve was suspected, and the patient was admitted to the institution.Warfarin was reintroduced on (b)(6) 2023.Echocardiogram result on (b)(6) 2023 showed max velo.=2.8 m/s, max pg=31.4mmhg, mean pg=16.7mmhg, eoa=0.9 cm2, dvi=0.28, at=100 msec.Ar trivial and the patient was discharged home on (b)(6) 2023.When the patient visited outpatient department on (b)(6) 2023, patient¿s respiratory distress had disappeared.Nt-probnp 762.8.On (b)(6) 2023, the patient visited the outpatient department.Nt-probnp 1027.4 epic is not explanted, and the anticoagulation therapy is being carried out.The patient is recovering.

An event of dyspnea, trivial aortic regurgitation and respiratory distress was reported.It was reported that thrombus was suspected on the valve.A more comprehensive assessment, including histopathological examination of the valve tissue could not be performed as the device was not returned for analysis.The device history record was also reviewed to ensure that each manufacturing and inspection operation was performed, and the product met all specifications.Based on the information received, the cause of the reported incident could not be conclusively determined.There is no indication of a product quality issue with respect to labeling design or manufacturing of the device.
